rural residential waste water/effluent treatment
I am developing a 48 lot rural residential subdivision set in 700
hectares of eucalypt timberland and improved and native pasture. The
layout comprises five clusters of 8-14 lots each set out along a
connecting road.
We intend to require each residence to install a conventional septic tank
to receive all waste water on a given lot , with the overflow of each
septic tank on each lot connected to a 90mm upvc pipe leading to a common
useage ponding system. The concept involves the construction of the first
pond so that an average depth of waste water of 1.2m is maintained with
retention of wate water in the first pond for a minimum 30 days
overflowing into a second pond for retention for a further 120 days. The
water then remaining may be used for spray irrigation in pasture.
The exposure of such waste water to sunlight should remove all bacteria.
Any persons having experience of such a system and knowledge of suitable
design parameters please contact me.
